Transformer

class capymoa.stream.preprocessing.Transformer

Bases: ABC

get_input_schema() → Schema

Return the schema of instances entering this transformer.

Defaults to get_schema() for transformers that do not alter the attribute set.

abstract get_schema() → Schema

Return the schema of instances leaving this transformer.

This is the schema the next element in a pipeline will receive, which is not necessarily the schema this transformer consumes – a filter may add, drop or rewrite attributes. See get_input_schema().
